I have a Mac book pro running version 10.7.2. I recently purchased Adobe CS5.5 Master Collection and proceeded to uninstal my previous version so that I could install the new one.

After downloading the 'demo' version and then trying to install it, I received an error message asking me to install the latest version of Air. I downloaded the latest version of Air and everytime I try to run it...I get an error saying that Adobe Air needs the latest version of Adobe Air in order to proceed with installation.

What the??? This is insane!! I tried all the various troubleshooting suggestions including inserting code in Terminal but nothing works!!

This is what I get when I try and install Adobe Air, totally doesn't make sense: "This application (Adobe Air) requires a version of Adobe Air which cannot be found. Please download the latest version (which I did...which is what I'm trying to install) of the runtime from http://www.adobe.com/go/getair, or contact the application author for an updated version.

Someone please help...is anyone else having issues? I have a year old Macbook Pro with the i7 Core Duo.

Wow...unreal, doing the update from Chrome to Adobe Air AND downloading/installing Adobe Master Collection fixed the problem instantly. Safari was the issue...very strange but very happy it's fixed now!

I uninstalled my downloaded version of master suit after the trail was over. I'm looking to use other programs that use this and I've tried everything that people have offered as advice. STILL the same error message.

Help! I need need need to order photos using another program that uses this and I can't do it!

I'm sorry you're running into installation issues with AIR. Microsoft has released a new utility that can help resolve installation problems. Would you mind giving this a try and let us know how it works for you? When running the Fix it, go through the uninstall process and try to remove Adobe AIR from your system. Once finished, download the latest version of AIR and install again.

Oops, sorry about that. Let's try this. Go to /Library/Frameworks/ and delete the Adobe AIR.framework folder. Once that's gone, try reinstalling the runtime from the .dmg and then give the .air file another go.

Ok I had the EXACT same problem you did! I was using Safari and it was telling me it couldn't install the Adobe Download Assistant because it needed Adobe Air, but when I tried to download Air, it gave me that message too. But I just downloaded Firefox and it worked just fine downloading Photoshop from there. I'm not sure what the deal is, but at least it's working now.

This is can affect any adobe app. and the bug fix should be prioritized appropriately.

I was using Adobe Muse (public 5) for a client project. I tried using Muse offline and this seems to have caused AIR (installed Nov 6) to corrupt. I could not get Muse or AIR to install until I disabled Automatic graphics switching.

Anyway, disabled Automatic graphics switching is a usable work around.

I'm sorry you guys are effected by this bug. I know it's a huge pain, and finding the solution is harder than it should be. We're working to get the workaround more visibility and we're also working closely with Apple to resolve it as quickly as possible.

Thanks for your reply. I like (and i belive that it likes all others too) to receive a reply from Adobe

I noticed that TweetDeck works well, while I have problems with Balsamiq Mockup and Creately.

The thing is very strange: i have to open first TweetDeck, so i have to wait for some minutes and than i can open other AIR apps.

If i open first Balsamiq or Creately i receive errors.

If i open first TweetDeck and than Balsamiq or Creately WITHOUT wait some minutes, i receive errors.

I discovered this writing this message.

Infact i remember that yesterday i opened first TweetDeck and than other apps and all works well.

Today i do the same procedure but the errors appeared.

So i came to this forum, logged me in and started to write. When i opened again the apps to see the errors to post them here, the apps worked, so i think that i have to wait some minutes... and i don't understand why, obviously! o.O

I have the same problem with my macbook pro. I read on a blog somewhere that if you turn off the automatic graphic switching in your system preferences/ energy saver section it will fix the problem. So I tried it and now it works fine
